ÆSIR is short for ”Association of Engineering Students In Rocketry” and is an THS Student Union association engaged in rocket and space systems development. It is a place to meet like-minded people and get hands-on experience of real-world engineering work. It is actually rocket science!

The association usually runs a main project in rocket development for 1.5 years simultaneously as other smaller space-related projects. The workload covers all from design and construction to testing and analysis. Our association goal is to build and launch rockets in order to break the European altitude record for amateur rocketry.
